It's always easier to destroy than to build, and that's a very helpless thing. The construction of the Earth will undoubtedly take more energy and time than the half-finished planetary battle stars built by the fifth-level civilization alliance, and the technology content is also higher, but if it collides with the half-finished planet battle stars of the fifth-level civilization alliance, the earth will also be destroyed, and its outcome will not be any different from the enemy's half-finished planet battle stars.

The energy that erupted from the planetary-level collision was not something that Xiao Yu could resist at this stage.

Xiao Yu didn't want to accept such a thing, so Xiao Yu only had one choice left, and that was to destroy the enemy planetary battle star! As long as it is destroyed, it will not be able to hit the Earth.

However, destroying a planetary battle star is not easy to say! Although it is a semi-finished product, it is also a planetary battle star after all, you must know that in the capital galaxy of the Pegasus civilization, Xiao Yu used a continental-level spaceship to impact at a speed of tens of thousands of kilometers per second to destroy the protective shield of the capital planet, and now, after nearly a thousand years of development, the scientific and technological level of the fifth-level civilization alliance has made great progress, and now it is so easy to destroy its planetary protective shield?

I'm afraid that even a direct collision of two, or even three continent-class spaceships, will not be able to achieve the goal. What's more, there is only one continental-class spaceship around the Earth now, which is still a conventional strength, and its performance cannot be compared with a spaceship like the Asia.

And most importantly, there is not much time left before two planets collide. At most, Xiao Yu has three hours left at most. If he can't turn the tide and change the situation in these three hours, Xiao Yu can only accept the reality that the Earth has been destroyed.

The situation has reached an extremely critical moment, but now Xiao Yu does not feel a little panicked in his heart. The reason is simple. Xiao Yu knew for a long time that there were planetary battle stars in the Flower of Death Galaxy, and even knew the number, orbit, performance and other data of these planetary battle stars, when he was manipulating the Earth into the Flower of Death Galaxy and rescuing the Asia spacecraft, how could he not have thought that the fifth-level Civilization Alliance might use the planet battle stars to hit the Earth?

Yes, Xiao Yu thought of this kind of thing early on, but Xiao Yu still chose to drive the Earth here. Because Xiao Yu is absolutely sure to deal with such a thing.

In the midst of the artillery fire in the sky and the ships shuttling everywhere. Xiao Yu's attention was focused on the point of light that was gradually becoming brighter.

Due to the presence of a large number of man-made structures, planetary battle stars generally have a high albedo, which means that they are inside the star system, close to the star. Planets reflect extremely bright light. Although now, space is full of artillery fire. Everywhere there was the glow of the ship's explosion. However, because the point of light representing the planet has always been stable, it is still conspicuous enough.

Xiao Yu was silently calculating the distance between this point of light and himself, and at the same time, he was silently preparing.

The planetary battlestar, the Earth, is about to exert his full combat effectiveness!

An hour and a half later. Judging from the Shili of an ordinary person on the Earth, the enemy planetary battle star has finally expanded from a point of light with no detailed information to a spherical object with vague stripes. It appears to be about one-tenth the size of the Moon as seen from Earth, with extremely bright stellar light reflected by it. So that Xiao Yu can easily perceive its existence.

There is less than half an hour left before the final collision.

"It's almost time, now." Xiao Yu calculated for a moment and came to this conclusion.

The situation now maintains a delicate balance. Although there are many warships besieging the Earth, under the strong protection of the four maintenance covers, as well as the strong counterattack power of conventional weapons, the Earth is not in danger for the time being. Xiao Yu can even draw out the super negative matter cannon and space weapons to prepare to deal with the upcoming big guy.

Xiao Yu's method of dealing with this half-finished planetary battle star is very simple, that is, to destroy it directly, without any fancy or any tricks, if you dare to approach, I will destroy you, it's that simple.

With 500 space weapons and 300 super negative matter cannons, the Earth has this qualification and strength. It was precisely because of this confidence that Xiao Yu still let the Earth enter the Flower of Death Galaxy even though he knew that he might encounter a half-finished planetary battle star impact.

"Let's get started, then." Xiao Yu gave the order.

The most violent attacks unfolded in an instant. On the surface of the Earth, countless busy robots and various mechanical equipment transported various resources to the 500 space weapon bases and 300 super negative matter cannon bases, and these resources finally converged on the space weapon launchers through a series of indescribable physical reactions under the guidance of various high-tech machines.

At this moment, something like lightning flashed here. After a dozen seconds of flickering, a thin black line began to form. It twisted its body in the transmitter as if it were alive, as if it were trying to break free from the machine's bondage.

After it struggled for a minute, it succeeded. Under Xiao Yu's manipulation, it was launched after it had grown strong enough. It is not a physical object in itself, so it is not bound by the theory of relativity, its speed can easily exceed the speed of light, and the moment it is launched, it has already passed through the shield layer, entered space, and then continues to move forward, cutting everything that dares to stand in its way, whether it is friend or foe, into two parts.

With it was the remaining four hundred and ninety-nine spatial rifts, as well as three hundred torrents of negative matter. These things, almost at the same time, bombarded this half-finished planetary battle star that was constantly approaching, made by the fifth-level civilization alliance.

Xiao Yu saw that the moment it was hit, its brightness suddenly increased, and then it quickly dimmed, as if flickering.

A salvo could not destroy the planetary shield of this planetary battle star, which was something Xiao Yu expected. So Xiao Yu didn't hesitate at all, and immediately launched a second salvo.

Building on planets means that there is an almost unlimited supply of energy, and with an unlimited supply of energy, space weapons and negative matter cannons can attack continuously and non-stop.

The frequency of the firing of space weapons and super negative matter cannons has been increased to the rate of almost one salvo in ten seconds. Originally, the half-finished planetary battlestar was half an hour's journey from Earth, but now it is less than five minutes away. This meant that in the short twenty-five minutes that it had been getting closer, it had already withstood one hundred and fifty salvos, each of which was five hundred spatial rift attacks and three hundred negative matter torrent attacks.

Although this semi-finished planetary battlestar also has an unlimited energy supply, the protective shield base on it really can't withstand the surging energy load requirements like ocean waves in a short period of time. They collapsed, and the planetary shield lost its energy supply and disappeared with it.

One hundred and fifty salvos from the Earth shattered the sturdy shell of this half-finished planetary battle star.

Xiao Yu's Jihua has already succeeded in the first step. This is just the first step. Because this planetary battle star is still rapidly approaching the Earth, in another five minutes, it will collide head-on with the Earth and die together.

So Xiao Yu immediately launched the second step of the battle. Compared with the first step of Jihua, the second step of Jihua is undoubtedly very simple.

Without the protection of the planet's shield, a planet, no matter how advanced the weapons equipped on the ground, is only a living target. Under Xiao Yu's control, a formation of 10,000 spaceships set off and began to move towards the planetary battle star.

After reaching the planetary battle star, the 10,000 ships encountered unimaginable sniping, and more than a million ships participated in the interception of the 10,000 ships. But unfortunately, a planet, after all, is too big, when attacking a planet, you don't even need to aim, just aim your weapon at the bottom and launch, and then you're good to go. Defending a planet without a planetary shield is the act of investing the most and gaining the least.

The remaining thousands of spacecraft began to fly at an ultra-low altitude in the face of heavy artillery fire, and in the process of flying at an ultra-low altitude, one after another ground-penetrating missiles were released. Some of these missiles were destroyed, while others managed to reach the ground. As soon as they touched the ground, these missiles were like thirsty fish seeing water, and immediately stabbed violently.

These ground-penetrating missiles are manufactured using the most advanced technology of the fifth-level civilization, and they are equipped with powerful digging machinery at the warhead site, and they can even neutralize the material in front of them with negative matter, opening the way for their own progress. At the tail of them, they are equipped with the most powerful engines that propel them underground.

According to the geological structure of this planet, Xiao Yu believes that it is not a problem for these ground-penetrating missiles to penetrate 3,000 kilometers underground. You know, the radius of this planet is only more than 6,000 kilometers.

These ground-penetrating missiles are equipped with the most suitable weapon for blasting, antimatter bombs.

That's right, all Xiao Yu has to do is blow up the entire planet.

After blowing you to pieces, how do I see you hitting me?

This is Xiao Yu's idea, very simple, very rough, but very effective. (To be continued......)
